i’d say get dizzee- boy in da corner, wiley- treddin on thin ice, good albums and easily available, with a lot of the sick instrumentals used on them- i really recommend listening to ruff sqwad- guns and roses vol 1 and 2, easy enough to find on youtube, bit trickier to find for download but they’re the sickest shit ever imo
beatmakers: wiley, dizzee, ruff sqwad (rapid, slix etc i think- white label classics has most of their classic beats and is easily available), danny weed, big shot, dj mondie, youngstar (pulse x is the classic), skepta, jme, alias, jon e cash, dj oddz + eastwood, jammer
mcs: wiley, dizzee, skepta, jme, d double e (newham generals), trim, riko, crazy t, durrty goodz etc
it’s really a genre that worked best on radio where u get the hype of the mcs spitting fast over the beats, when u listen to 8 bar style instrumentals too long it can get boring, there’s a million sick sets up on youtube and they’re probably your best starting point- id say try something like wiley, dizzee, slimzee, or just roll deep- shit before 2004/5 i find is best
